328 CHAPTER 24 24.55 (a) If light has wavelength λ in vacuum, its wavelength in a medium of refractive index n is n n λ λ = . Thus, the wavelengths of the two components in the specimen are 1 1 546.1 nm 413.7 nm 1.320 n n λ λ = = = and 2 2 546 nm 409.7 nm 3 n n .1 1.33 λ λ = = = (b) The number of cycles of vibration each component completes while passing through the specimen are 1 -6 1 -9 1.000 10 m 2.417 413.7 10 m n t N λ × = = = × and 2 -6 2 -9 1.000 10 m 409.7 10 m n t N λ × = = × 2 1 0.024 cycles N N = ( 2.441 = Thus, when they emerge, the two components are out of phase by . Since each cycle represents a phase angle of 360°, they emerge with a phase difference of ) ( ) = 0. φ 024 cycles 360 cycle 8.6 ° = ° 24.56 Bright lines occur at angles given by ( ) sin m d θ λ = . Thus, if the bright line of wavelength 4 m = 1 λ and the
